Abstract:
In terms of the exploration of coal and coalbed methane, the advantage is a high exploration degree of coal and coalbed methane (CBM) and the disadvantage is a high overlap rate of mining right for CBM exploration and development in a coal mining area.Therefore, the study of spatial-temporal relationship of exploration and development is of significance for the safe and efficient coordination development of CBM and coal in a coal mining area.Based on the comprehensive analysis of the spatial-temporal replacement characteristics of coal and the present mining right situation of coal and CBM, with coal mine or exploration area as a basic unit, Huainan-Huaibei coalfield can be divided into seven different blocks.Based on the system analysis of the exploration and development sequence of CBM and coal and the development mode of CBM, combined with CBM geological conditions, with the spatial and sequence arrangement as mainline, this paper discussed the exploration and development principle of CBM and coal, the development mode of CBM, the distribution of key blocks, the gas bearing area, and the quantity of resource, and built up the pattern of spatial-temporal collocation for CBM and coal.The study provided a technical solution for the mining right overlap, and also provided a theoretical direction for the coordinated development of CBM and coal in Huainan-Huaibei coalfield.
